Software Testing Basics for beginners

• Software Testing Basics for beginners
• Software testing can be stated as the process of
  verifying and validating that a software or
  application is bug-free, meets the technical
  requirements, how its design and development,
  and meets the user requirements effectively and
  efficiently with the handling of all exception
  cases and edge cases.
• The process of software testing not only aims to
  find errors in the existing software, but also
  to find measures for the improvement of the
  software in terms of efficiency, accuracy, and
  usability. It mainly aims to measure the
  specification, functionality and performance of
  a software program or application.
• Software Tests can be divided into two steps
• Verification it refers to the tasks that ensure
  that software correctly implements a specific
  function.
• Validation it refers to another set of tasks
  that ensure that the software that was built is
  traceable to customer requirements.
• Verification "do we build the product right?
  Validation "do we build the right product?
• What are different types of software testing?
  Software Tests can be roughly divided into two
  types
• Manual Testing Manual testing includes manual
  testing of a software, i.e., without automated
  tool or script. In this type, the tester assumes
  the role of an end user and tests the software
  to identify unexpected behavior or errors. There
  are different levels for manual Tests such as
  unit Tests, integration tests, system tests and
  User Acceptance Tests.
• Testers use test plans, test cases, or test
  scenarios to test software to ensure that the
  Tests are complete. Manual testing also includes
  exploratory testing as testers explore the
  software to identify errors in it.
• Automation testing automation testing, also
  known as test automation, is when the tester
  writes scripts and uses another software to test
  the product. This process involves the
  automation of a manual process. Automation tests
  are used to rerun the test scenarios that were
  performed manually, quickly, and repeatedly.

In addition to regression tests, automation tests
is used to test the application from load,
performance and stress point of view. It
increases test coverage, improves accuracy, and
saves time and money compared to manual
Tests. https//www.exltech.in/software-testing-c

• What are different techniques of software
  testing?
• Software techniques can be divided into two main
  categories
• Black Box Testing the technique of testing where
  the tester does not have access to the source
  code of the software and is performed at the
  software interface without affecting the
  internal logical structure of the software is
  called black box testing.
• White-Box Testing the technique of testing in
  which the tester of the internal workings of the
  product, have access to its source code, and will
  ensure that all internal operations are
  performed according to the specifications known
  as white box testing.
• What are different levels of software testing?
• Software level testing can be majorly classified
  into 4 levels
• 1. Unit Testing a level of the software testing
  process where individual units/components of a
  software/system are tested. The purpose is to
  verify that each unit of the software performs
  as designed.

• What do you mean? Integration test a level of
  the software test process in which individual
  units are combined and tested as a group. The
  purpose of this Test level is to detect errors
  in the interaction between integrated units.
• System test a level of the software test process
  in which a complete integrated system/software
  is tested. The purpose of this test is to assess
  the conformity of the system with the specified
  requirements.
• Acceptance test a level of the software testing
  process in which a system is tested for
  acceptance. The purpose of this test is to assess
  the system's compliance with business
  requirements and to assess whether it is
  acceptable for delivery.
